Summary of Invention

Problems to be Solved by the Invention

When chapters are automatically added, the automatically added chapters are not necessarily added to positions at which chapters originally need to be added. Depending on cases, there are also cases where chapters may be added to positions at which chapters should not be added.
There is also a method of manually allocating chapters per scene while a predetermined operator is looking at a video image to add chapters to more correct positions. Information including chapters manually added per scene by such a predetermined operator is provided as scene data on a server, so that a broadcast recording device can acquire the scene data from the server through the Internet.
An object of the present disclosure is to provide a recording device which receives scene data from an external device and can notify a user of a possibility of adding scene data.

Means for Solving the Problem

A recording device of the present disclosure includes a recording unit that records moving image data in a recording medium, a transmitting unit that transmits a request signal for requesting scene data to an external device, the scene data being information in which a chapter indicating a time position is added for each of scenes in relation to the moving image data recorded in the recording medium, a receiving unit that receives a response signal in response to the request signal from the external device, and an output unit that outputs image data indicating a message when the receiving unit cannot receive the scene data in response to the request signal from the external device. The message is changed according to an elapsed time from a time at which the moving image data is recorded in the recording medium by the recording unit.
A message display method of the present disclosure is a message display method of displaying a message in response to a response result when scene data related to moving image data is requested to an external device. The scene data is information in which a chapter indicating a time position is added for each of scenes of the moving image data. The message display method includes transmitting to the external device a request signal for requesting scene data related to specific moving image data recorded in the recording medium, outputting image data indicating a message when the scene data in response to the request signal cannot be received from the external device, and changing the message according to an elapsed time from a time at which the moving image data is recorded in the recording medium.
A program of the present disclosure is a program of controlling a recording device which records scene data related to moving image data. The scene data is information in which a chapter indicating a time position is added for each of scenes of the moving image data. The program makes a controller of the recording device execute the following functions:

a function of transmitting to the external device a request signal for requesting scene data related to specific moving image data recorded in the recording medium;
a function of outputting image data indicating a message when the scene data in response to the request signal cannot be received from the external device; and
a function of changing the message according to an elapsed time from a time at which the moving image data is recorded in the recording medium.

Effects of the Invention

According to the present disclosure, it is possible to provide a recording device which, in cases where scene data is generated within a predetermined time after a program corresponding to moving image data (program data) is broadcasted, can notify a user of a possibility of allocating scene data to the moving image data.

First Embodiment

1-1. Outline

An entire configuration of a recording system including a recorder according to the present embodiment will be described with reference to Fig. 1. This recording system includes a recorder 100, a television 500 and a server 700. The recorder 100 can communicate with the server 700 through an Internet 600.
The server 700 stores scene data. The scene data is information indicating content (features) of a program for each of scenes. The scene data is created by a predetermined operator who actually views a program indicated by program data, judges content of the program, and manually adds the scene data for each scene. For example, for a program which starts at 00:00, scene data indicating that a scene at 00:00 to 00:10 is an opening of a drama, scene data indicating that a scene of 00:10 to 00:11 is a commercial message of a beer, and scene data indicating that a scene of 00:11 to 00:12 is a commercial message of a supermarket, are created respectively. The scene data includes a chapter indicating a scene change point. That is, a chapter is added to a point at which scenes switch.
The recorder 100 can acquire scene data related to program data to be played back from the server 700 through the Internet 600. The recorder 100 generates chapter information from the acquired scene data upon acquisition of scene data. The recorder 100 can execute skip playback on the basis of the chapter information. Here, the skip playback is an operation of changing a playback position on the basis of chapter managed by chapter information included in the scene data.
Further, the recorder 100 can receive broadcast. The recorder 100 can record program data generated on the basis of the received broadcast, in an internal hard disk. When recording program data, the recorder 100 automatically adds chapters to program data when predetermined conditions (e.g. start/end of commercial messages) are satisfied. At that time, the recorder 100 generates chapter information which manages automatically added chapters. The recorder 100 can execute skip playback on the basis of the chapter information for managing the automatically added chapters.
As described above, chapters which are scene change points include two types of chapters including a chapter generated on the basis of scene data and a chapter automatically added on the basis of the predetermined conditions. Thus, a plurality of types of chapters are likely to be added to one piece of program data. In this case, when a skip playback command is received from a user, it is difficult to determine which type of chapter indicates a position to which a playback position is changed. That is, there is a problem that it is not possible to distinguish between skip playback based on a chapter (chapter information) generated on the basis of scene data and skip playback based on a chapter (chapter information) automatically added on the basis of the predetermined condition and to execute them apart.
The recorder 100 according to the present embodiment can solve such a problem. Even when a plurality of types of chapters are mixed and added to one program data, the recorder 100 can execute apart the skip playback based on a chapter generated on the basis of scene data and the skip playback based on an automatically added chapter.

1-2. Configurations of Recorder and Remote Controller

Configurations of the recorder 100 and a remote controller 200 will be described with reference to Fig. 2. Fig. 2 is a view illustrating the configurations of the recorder 100 and the remote controller 200. The recorder 100 applies with a microcomputer 130 various types of processing to broadcast data received by a tuner 110 according to a command from a user through the remote controller 200 to generate program data, and records the generated program data in a HDD 140. The recorder 100 transmits program data recorded in the HDD 140, to an external device through a HDMI 150. Each of components will be described in detail below.
In the recorder 100, the tuner 110 extracts broadcast data of a channel selected by the user from broadcast data received through an antenna. The tuner 110 generates digital data which can be processed by the microcomputer 130 on the basis of the extracted broadcast data.
A remote control signal receiving unit 120 receives a control signal modulated to an infrared ray or an RF wave transmitted from the remote controller 200. For example, the remote control signal receiving unit 120 receives control signals of power ON/OFF, channel selection, playback start/stop, skip playback, and so on. The remote control signal receiving unit 120 converts the received control signal into a digital signal which the microcomputer 130 can interpret.
The microcomputer 130 is a control module which controls entirely the recorder 100. The microcomputer 130 is made by a SOC (System On Chip). Hence, the microcomputer 130 is made integrally with a CPU, a memory, and a data signal processing circuit.
The HDD 140 is a storage device which stores moving image data and the like. The HDD 140 stores program data indicating a broadcast program received through the tuner 110, chapter information which is information related to chapters automatically added to the program data, and the like.
The HDMI 150 is an interface which connects the recorder 100 and the external device such as the television 500. The recorder 100 outputs program data indicated by a broadcast program stored in the HDD 140, and so on to the external device (e.g. a television 500) through the HDMI 150.
A wired LAN module 160 is an interface which can be connected with a LAN cable. The recorder 100 can be connected to the Internet through the LAN cable by the wired LAN module 160.
A flash memory 170 is a recording medium which stores a control program of the recorder 100, scene data received from an outside through the wired LAN module 160, and so on. The flash memory 170 stores chapter information related to chapters generated on the basis of scene data, too.
The remote controller 200 includes buttons 210, 220, 230 and 240 pushed by the user to command the recorder 100 to execute a predetermined function. The button 210 is a button for skipping program data which is being played back, in a forward direction. The skip commanded by the button 210 is executed on the basis of a chapter automatically added by the recorder 100. A button 220 is a button for skipping program data which is being played back, in a backward direction. The skip commanded by the button 220 is executed based on chapters automatically added by the recorder 100. The button 230 is a button for skipping program data which is being played back, in the forward direction. The skip commanded by the button 230 is executed on the basis of chapters generated from scene data acquired from an outside through the wired LAN module 160. The button 240 is a button for skipping program data which is being played back, in the backward direction. The skip commanded by the button 240 is executed on the basis of scene data acquired from the outside through the wired LAN module 160. As described above, in the present embodiment, the skip based on an automatically added chapter and the skip based on a chapter generated on the basis of scene data are commanded by different operation buttons (210 and 220, and 240 and 240).

1-3. Chapter Information and Scene data

Figs. 3A and 3B are views for explaining chapter information for managing automatically added chapters. As illustrated in Fig. 3A, the chapter is sequentially added to a position (change point) at which attribute of program data (video stream) changes. For example, the chapter is added to time point at which content switches to a CM (Commercial Message), time point at which the contents switches, and time point at which a CM switches to the content.
Fig. 3B is a view explaining a configuration example of chapter information. As illustrated in Fig. 3B, information indicating a playback time to which a chapter is added is associated with program data (video stream), in the chapter information. The playback time to which a chapter is added is information indicating a relative time position, using a playback start time of each program data as a reference time (0). Information indicating "5 minutes" of a stream 1 illustrated in Fig. 3B indicates that a chapter is added to a time position of five minutes elapsing from the playback start time of the stream 1, and information indicating "10 minutes" indicates that a chapter is added to a time position of 10 minutes elapsing from the playback start time of the stream 1.
Figs. 4A to 4C are views for explaining the scene data. Fig. 4B illustrates an example configuration of the scene data received by the microcomputer 130 of the recorder 100. The scene data is configured by information indicating a start time, an end time and scene content related to each scene in program data, and a start time, an end time and CM content of each CM. The scene data is information generated by the predetermined operator viewing a program indicated by target program data. Hence, the chapter can be added not only to a boundary between a content portion and a CM portion in a program, but also to a switching point of scenes in the content portion and a boundary at which a type of CM changes. That is, as illustrated in Fig 4A, the chapter is added to a point at which scenes and CMs change in the scene data. Time information indicating a start time and an end time of each scene and each CM in the scene data is information indicating an actual time (absolute time) at which the associating program data is broadcasted. When the scene data is received from the server 700, the chapter information (see Fig. 4C) indicating a chapter position with a relative time position is generated on the basis of the scene data.

1-4. Chapter Automatic Allocating Operation

As described above, in the present embodiment, there are two types of chapters which are change points of scenes including the chapter generated on the basis of the scene data, and the chapter automatically added on the basis of the predetermined condition. An operation of the recorder 100 of automatically allocating chapters on the basis of the predetermined condition will be described below with reference to Fig. 5.
Fig. 5 is a flowchart for explaining an automatic chapter allocating operation.
In the flowchart in Fig. 5, when a record command is received from the user, the microcomputer 130 of the recorder 100 starts recording program data generated on the basis of broadcast data received through the tuner 100, in the HDD 140 (S100). When recording of the program data starts, the microcomputer 130 determines whether or not an attribute of the recorded program data (video stream) changes (S110). For example, the microcomputer 130 determines whether or not an audio signal of the program data changes from a monaural sound to a stereo sound or vice versa. When determining that the attribute changes, the microcomputer 130 records management data corresponding to the program data which is being recorded (information indicating a time position (change point) at which the attribute changes in chapter information), as chapters, in the HDD 140 (S120). For example, as illustrated in Fig. 3A, a chapter is sequentially added to a position (switch point) at which attribute of program data (video stream) changes. In the present embodiment, the management data is recorded in the HDD 140.
When recording of the program data in the HDD 140 is finished, chapter information related to program data as illustrated in Fig. 3B is generated. The recorder 100 can execute skip playback by referring to chapter information stored in the HDD 140 when playing back program data.
As described above, when the program data is recorded, chapters are automatically added to program data. As illustrated in Fig. 6, chapter information 51 for managing chapters automatically added is recorded in the HDD 500.

1-5. Acquiring Operation of Scene data

Next, an operation of the recorder 100 for acquiring scene data from the server 700 will be described with reference to Figs. 7 to 9. Fig. 7 is a flowchart for explaining an operation of acquiring scene data. Fig. 8 is a schematic diagram for explaining an example of a warning screen 1. Fig. 9 is a schematic diagram for explaining an example of a warning screen 2.
A "scene playback mode" described below refers to a playback mode of executing skip playback of program data using scene data. Program data to be played is program data stored in advance in the HDD 140.
When the program data to be played is selected by the user while the scene playback mode is set (S200), the microcomputer 130 of the recorder 100 determines whether or not the selected program data is program data generated on the basis of broadcast data received through the tuner 110 and unedited program data (S210). This determination is performed because scene data of video data (e.g. video data shot by the user with a video camera) which is not a broadcasted program is not stored in the server 700. Further, scene data corresponding to edited program data is not stored in the server 700.
When determining in step S210 that the selected program data is not broadcasted program data or is edited program data, the microcomputer 130 controls the HDMI 150 to output image data indicating a message (warning screen 1) as illustrated in Fig. 8 (S220). The message included in this warning screen 1 is a message which notifies the user that scene data is not added to program data selected as a program data to be played even in the future.
Meanwhile, when determining in step S210 that the selected program data is broadcasted program data and unedited data, the microcomputer 130 transmits a scene data request command to the server 700 through the wired LAN module 160 (S230).
When receiving the command of requesting scene data, the server 700 determines whether or not there is scene data corresponding to the program data to be played in the server 700. When determining that there is not the scene data, the server 700 transmits error data to the recorder 100 as a response to the scene data request command. The error data indicates that there is no requested scene data on the server 700.
When receiving the error data (YES in S240), the microcomputer 130 of the recorder 100 determines whether or not a predetermined time (e.g. 26 hours) has passed after recording of the program data to be played (S250). When it is determined that the predetermined time (e.g. twenty-six hours) passes, the microcomputer 130 controls the HDMI 150 to output image data indicating the warning screen 1 (S260). Meanwhile, when determining that the predetermined time (e.g. twenty-six hours) does not pass, the microcomputer 130 controls the HDMI 150 to output image data indicating a message (warning screen 2) as illustrated in Fig. 9 (S270). A message included in this warning screen 2 is a message which notifies the user that scene data is not added to program data selected as program data to be played, that is, there is a possibility of allocating scene data to selected program data in the future.
The reason for determining whether or not the predetermined time (e.g. 26 hours) passes in step S250 is described below. Scene data is manually created for each scene by the predetermined operator who actually views a program and determines content of the program. It takes time to create the scene data, and therefore a certain time for preparing the scene data is secured after the program is broadcasted. In the present embodiment, when scene data of a broadcasted program is created, scene data is created within the predetermined time (e.g. 26 hours) from a time at which a scene is broadcasted. In view of such matter, in step S250, it is determined whether or not the predetermined time (e.g. 26 hours) passes from a time of the recording in order to determine whether or not there is a possibility of creating scene data for this program.
Although, in step S250, a reference time for the elapsed time is a time at which the program data to be played is recorded, the reference time for the elapsed time is not limited to this. A time shifted forward or backward from a time at which the program data to be played is recorded may be used as the reference time. That is, a time which can be associated with a broadcast time of a scene can be used as the reference time.
Meanwhile, in step S240, when there is scene data in the server 700, the server 700 transmits scene data to the recorder 100 (NO in S240). The microcomputer 130 of the recorder 100 receives the scene data through the wired LAN module 160 (S280).
The microcomputer 130 of the recorder 100 executes processing of converting the received scene data to generate chapter information and records the generated chapter information with the received scene data in the flash memory 170 (S290). More specifically, in the converting processing, information (see Fig. 4B) indicating an absolute recording time of a chapter is converted into a relative time (see Fig. 4C) with respect to a playback start position.
Thus, in the present embodiment, as illustrated in Fig. 6, the scene data 53 received from the server 700 and chapter information 55 generated from the scene data are recorded in the flash memory 170.
As described above, the recorder 100 according to the present embodiment distinguishes between chapter information (first chapter information) related to a chapter automatically added and chapter information (second chapter information) based on the scene data and record them apart. That is, as illustrated in Fig. 6, the recorder 100 records in the HDD 140 the chapter information 51 related to a chapter automatically added, while recording in the flash memory 170 the chapter information 55 generated on the basis of the scene data received from the server 700. With this arrangement, the recorder 100 can execute skip playback on the basis of either one of the chapter information (first chapter information) related to a chapter automatically added and the chapter information (second chapter information) based on the scene data. Since the first chapter information and the second chapter information are recorded in different recording media, the recorder 100 can switch a type of chapter to be used upon execution of skip playback only by changing the recording medium to access.
When receiving error data indicating that there is no scene data, from the server 700, the recorder 100 according to the present embodiment switches a type of a warning screen to output depending on whether or not the time passed from a time at which program data is recorded is within the predetermined time (e.g. twenty-six hours). Consequently, the recorder 100 can accurately notify the user whether or not there is a possibility of allocating scene data in the future.
In the present embodiment, although the first chapter information for managing automatically added chapters and the second chapter information based on the scene data are recorded in the different recording media, the recording way of the first chapter and the second chapter are not limited to such a configuration. For example, as illustrated in Fig. 10, the first chapter information 51 and the second chapter information 55 may bye recorded in the same recording medium (e.g. the HDD 500). In this case, respective pieces of chapter information need to be managed to enable distinction between the first chapter information and the second chapter information. For example, the first chapter information and the second chapter information may be configured by different tables. Further, in order to distinguish between the first chapter information and the second chapter information, the first and second chapter information may be managed by adding identifiers to the first chapter information and the second chapter information, respectively, and associating each identifier with program data.

1-6. Skip Playback Operation

A skip playback operation in a scene playback mode of the recorder 100 will be described with reference to Fig. 11. Fig. 11 is a flowchart for explaining the skip playback operation in the scene playback mode using the remote controller 200.
When a playback operation in the scene playback mode is started in the recorder 100 (S300), the microcomputer 130 determines which one of the buttons 210 to 240 of the remote controller 200 is pressed by the user on the basis of a signal received through the remote control signal receiving unit 120 (S310).
When determining that the button 220 is pressed, the microcomputer 130 sets a playback position to a position of a chapter appearing first in a backward direction from the current playback position on the basis of the second chapter information stored in the HDD 140, and resumes playback from the set playback position (S320).
When determining that the button 240 is pressed, the microcomputer 130 sets a playback position to a position of a chapter (previous scene) appearing first in the backward direction from the current playback position on the basis of the first chapter information included in the scene data stored in the flash memory 170, and resumes playback from the set playback position (S330).
When determining that the signal indicates that the button 230 is pressed, the microcomputer 130 sets a playback position to a position of a chapter (next scene) appearing first in the forward direction from the current playback position, on the basis of the first chapter information included in the scene data stored in the flash memory 170, and resumes playback from the set playback position (S340).
When determining that the signal indicates that the button 210 is pressed, the microcomputer 130 sets a playback position to a position of a chapter appearing first in the forward direction from the current playback position, on the basis of the second chapter information stored in the HDD 140, and resumes playback from the set playback position (S350).
As described above, for the recorder 100 according to the present embodiment, a skip operation commanding function is added to each of buttons 210 to 240 of the remote controller 200. With this arrangement, the remote controller 200 can command the recorder 100 separately to execute skip playback based on the first chapter information (chapter automatically added) and to execute skip playback based on the second chapter information (chapter generated from scene data).

1-7. Effect, etc.

As described above, in the present embodiment, the recorder 100 has the recording media such as the HDD 150 and the flash memory 170, the microcomputer 130 which controls the operation of the recorder 100, and the wired LAN module 160 which communicates with the server. The microcomputer 130 detects time position in program data (moving image data) matching with the predetermined condition, adds a chapter to the detected time position, and generates the first chapter information 51 for managing the chapter. The microcomputer 130 receives from the external device through the wired LAN module 160 the scene data 53 in which the chapters indicating time positions are added for each scene of the moving image data. The microcomputer 130 records the first chapter information generated by the microcomputer 130 and the second chapter information generated on the basis of scene data received by the wired LAN module 160, respectively in the recording media. The first chapter information and the second chapter information are managed to be distinguishable therebetween. More specifically, the first chapter information and the second chapter information are respectively recorded in the different recording media (the HDD 500 and the flash memory 170).
According to the above configuration, it is possible to distinguish between and refer to the first chapter information and the second chapter information even when the first chapter information and the second chapter information are recorded in the recorder 100.
Further, in the present embodiment, the recorder 100 has the microcomputer 130 which records program data in the HDD 140, and the LAN module 160 which communicates with the server 700. The microcomputer 130 transmits a request signal for requesting scene data in which a chapter indicating time position is added for each scene in relation to program data recorded in the HDD 140, to the server 700 through the LAN module 160. The microcomputer 130 receives a response signal to the request signal from the server 700 through the LAN module 160. The microcomputer 130 outputs image data indicating a message when the microcomputer 130 cannot receive scene data in response to the request signal from the server 700. The microcomputer 130 changes a message according to an elapsed time from a time at which program data is recorded in the recording medium.
In cases where scene data is generated within a predetermined time after a program corresponding to program data is broadcasted, according to the aforementioned configuration, it is possible to provide the user with information as to whether or not there is a possibility of adding scene data to the program data.

Other Embodiments

The first embodiment has been described as an exemplary technique disclosed in the present application. However, the technique according to the present disclosure is not limited to this, and is also applicable to embodiments to which adequate changes, substitutions, additions and omissions are applied. Hereinafter, other embodiments will be described below.
Although a recorder has been described as an example of a recording device in the first embodiment, the idea of the present disclosure is applicable to arbitrary devices as long as the devices record program data and scene data.
Further, although a recorder 100 generates the second chapter information from the scene data received from the server 700 in the first embodiment, the recorder 100 may receive the scene data and the second chapter information from the server 700.
Furthermore, although an example where connection to the Internet is established through a wired LAN has been described in the first embodiment, the connection to the Internet may be established through a wireless LAN or another communication interface.
Moreover, although a HDD and a flash memory have been described as a recording medium which record the chapter information in the first embodiment, the recording medium is not limited to these. For example, an optical disk, such as DVD (Digital Versatile Disc) and BD (Blu-ray Disc), and/or a memory card having semiconductor memory elements inside may be used.
Further, in the first embodiment, the step S210 in Fig. 7 determines whether or not the program data to be played is broadcasted program data and unedited program data. However, performing determination is not necessarily limited to such a configuration. For example, it may be determined only whether or not the program data to be displayed is broadcasted program data. In this case, when the broadcasted program data has been edited, a request to transmit the scene data is sent to the server. Alternatively, it may be determined whether or not the program data to be played is broadcasted program data and program data obtained by combining plural pieces of program data. In this case, when the broadcasted program data is program data to which editing processing other than combining of plural pieces of program data is applied, such as partially deleting program data, a request to transmit the scene data is sent to the server.
As described above, the above embodiment has been described as the exemplary technique of the present disclosure. The accompanying drawings and the detailed description have been provided for the exemplary technique.
